IMPROVEMENT IN LQOMS FOR WEAVING PELE FABRICS.

Specification forming part of Letters Patent No. 3l,l97, dated September l0, 1872.

SPECIFICATION.

-I, WILLIAM WEBSTER, of Morrisania, in the county of Westchester and State of New York, have invented certain Improvements in Looms for Weaving Pile Fabrics, Snc., of which the following is a specification:

V'.Ihe nature of my invention consists, iirst.in the combination of a longitudinal wire support having two grooves, one for the withdrawing of the wire from out the cloth and the other for inserting the wire into the open shed of the transferring sliding-block, having one groove, whose length corresponds with the length of the wire-heads. This block slides across the end of the two wire grooves in or on a guide slide-path in such a way that when a wire is drawn out of the cloth into the iirst groove-the groove in the block being opposite to it-the head of the wire will be drawn into it, and the block is then slid with its wire head vand wire (the point of the wire being carried over or across the two grooves to the open shed by a lever or any well-known device not shown) opposite to, and then pushed into the second or inserting groove into the open shed, and the wire head into the wire-box; second, the combination, with the transferring sliding-block of a spring, a lever with its link connection, and at the end of this lever a spring-trip, so arranged and operating relatively to the lever that when a wire is being withdrawn from the cloth by the latch and reciprocating driving-slide, the inner under-side part of the slide comes in contact with the end of the trip moving it along, thereby releasing its hold of the end of the lever, with its link, to

v which is attached the block, and the block is then slid across with its wire opposite to the second or inserting groove, and on being pushed forward bythe pusher and drivingslide into the open shed, the inner under side of the driving-slide comes in contact with and moves the end of the lever outward, and the other .part of the lever, with its link connection, moves the block with its groove back again opposite to the first or withdrawing groove, when the end of the lever will again be caught and held by the trip, as before;

Y third, in the combination of the wire support,

having two grooves, driving-slide, pusher, and two latches-one latch to withdraw the wire from out the cloth into the first or withdrawing groove, the second latch to prevent the wire from being pitched out of the second or inserting groove while being pushed into the open shed, and also prevents the head of the wire leaving the pusher when the loom is reversed, by catching over or into a nick made in the head of the wire.

Description of the Accompanying Drawing.

Figures 1,2, and 3 represent a front, plan, and side view of a loom having my improvev ments connected therewith. Figs. 4 and 5 are plan and side views, showing the several parts as constructed, connected and operated. The devices on the under side of the wire support are shown in Fig. 4. in dotted lines, and with the lever J in its two positions. Fig. 6 is an end view of a part of the same. Fig. 7 is an end of the wire-box. Fig. 8 is a plan view of the driving-slide, pusher, and two latches.

In the drawing- A represents a longitudinal wire support, having two wire grooves, B and C, in its top surface, one for the withdrawing of the wire -D from out the cloth, the other or second groove for inserting of the wire into the open shed. The depth of these grooves is made according to circumstances; the wire support is attached to the loom in lany of the wellknown ways. E represents a block having a groove, F, in its top, and of the same width and depth as the grooves B and C. This block isA made to slide in or upon guide-paths G and H, and is slid across and opposite to the wiregroove C by the spring I, lever J, and link K,-

as soon as the end of the lever has been released i'rom the trip L, which is done by the pin M on the inner under side, or by the inner under side of the driving-slide N coming in contact with and bearing against it and pushing it oft the end of the lever, and the action of the spring I will force the lever with its block over', as shown in dotted lines. On the wire being pushed forward and into the open shed, and the head of the wire into the wirebox B', the same inner under side of the driving-slide comes in contact with the end of the lever at a, pressing it outward, which will again cause the other end of the lever with its block to be moved or slid back and opposite to the groove B, when the lever will be caught and held by the trip, actuated by the spring b, so that when another wire is withdrawn into the groove B the groove F in the block will be opposite to it, and the head of the wire will be drawn into it, and the end of the lever released from the trip by the driving-slide, as before. The driving-slide is reciprocated upon a slide pathway, A1, by a lever, A2, or any other well-known device. The point of the wire is carried across the grooves to the open shed by a lever or some other well-known device not shown. A3 represents the pusher attached to the driving-slide. A4 and A5 represent two latches, the first to withdraw the wire from out ofthe cloth into the Wire-groove B and groove F in the block E, and when the block has been slid across and the wire is being pushed forward in the wire-groove C, the other or second latch, A5, prevents the wire being pitched out of the wire-groove, and also prevents the wire-head leaving the pusher when the loom is reversed by catching over or into a nick made in the head of the wire.

As a modification to part of my improvement I propose to dispense with the spring, lever, and trip, and substitute in their place a lever, said lever being connected to the block and operated -by a cam upon the tappet or driving-shaft.

Having described the nature and operation of my improvements, I wish it to be understood I do not expect to confine myself to the precise forms or shapes of the several parts described.

I claiml. The combination, with the wire support, having two grooves, B and C, of the transferring sliding-blockvE, having a groove, F, when constructed and operating with relation to each othersubstantially as and for the purpose set forth.

2. In combination the transferring slidingblock E, spring I, lever J, with its link K, spring-trip L, and driving-slide N, all constructed and operating with relation to each other, substantially as and for the purpose set forth.

3. In combination with the wire support, having two grooves, B and C, driving-slide N, pusher A3, and two latches, A4 and A5, when constructed and operating with relation to each other, and adapted to move the wire, substantially as described.
